6.1 ACM-24AT, ACM-48A, and Expanders

6.1.1 Acknowledge/Lamp Test Switch

This switch's functions vary between ACM-24AT and AEM-24AT:

•

If this switch on the ACM-24AT is pressed and held for 2 seconds, it performs a lamp test for the annunciator and each connected

expander. LEDs light steady and piezo sounds for as long as the switch is held down.

•

If this switch on the AEM-24AT is pressed and held for 2 seconds, it performs a lamp test for the expander.

•

If this switch on the ACM-24AT is pressed quickly and released, it acknowledges all status changes for both the ACM-24AT and the

expanders. Flashing LEDs will glow steady and the piezo will be silenced.

NOTE: In systems set for manual override mode, it also functions as the manual override key to toggle between automatic operation or

manual override operation for all points.

•

Pressing and quickly releasing this switch does not have a function on an expander.

6.1.2 On-line LED

Lights steady green during communication with the control panel.

6.1.3 System Trouble LED

Glows yellow for all trouble conditions in the system, including points or zones not mapped to the annunciator/expanders. Flashes if commu-

nication with control panel is broken.

NOTE: In systems capable of manual override, this LED may be used to indicate manual override mode.

NOTE: If annunciator is set for Flash-inhibit, this LED will be on steady for unacknowledged events.

6.1.4 Control Switch

Functions as a local Lamp Test for the two LEDs dedicated to a point. Control switches can be used to execute such system functions as

ACKNOWLEDGE, SIGNAL SILENCE, and SYSTEM RESET. Switches can also be used to control the states of various output circuits.

Switches are used to select color of LEDs; see Section 5.15.1, "Selecting LED Colors: ACM-24AT and AEM-24AT".

NOTE: If annunciator is set for Switch-inhibit, these switches will not be able to execute system control functions; see appendix section for

your fire alarm control panel.

6.1.5 Point Active LED

On steady to indicate an active point; after being acknowledged it glows steady until reset.

NOTE: In Speaker and Telephone Mode, this LED will flash to indicate an active point.

NOTE: In Speaker Control Mode, this LED works differently; see Section 5.12.4, "Speaker Control Mode".
